As there are no additional symbolic links in this case, there's no

Why use :A --- for exactly the same reason you'd ever use it, that you
want the physical path for later reference rather than one that still
has symbolic links in it.  Why you'd do *that* is a vaguer question: you
might believe that the symbolic link was temporary and the physical
path not (which doesn't reflect the situtation I've got here in the

The result would differ if you had a symbolic link higher up, e.g. if my
home directory was a symbolic link (from an automounter, for example),
which would be resolved in one case but not the other.  But the question
